Smoothed l0 Norm Regularization for Sparse-View X-Ray CT Reconstruction
Low-dose computed tomography (CT) reconstruction is a challenging problem in medical imaging. To complement the standard filtered back-projection (FBP) reconstruction, sparse regularization reconstruction gains more and more research attention, as it promises to reduce radiation dose, suppress artifacts, and improve noise properties. In this work, we present an iterative reconstruction approach...
متن کاملCombined shearlet and TV regularization in sparse-view CT reconstruction
Preclinical in vivo micro computerized tomography suffers from high image noise, due to limitations on total scanning time and the small pixel sizes. A lot of different noise minimization algorithms have already been proposed to reconstruct images acquired in low dose settings. Sparse-view reconstruction amongst others can reduce acquisition dose significantly, by acquiring only a small subset ...
متن کاملRandomized Iterative Reconstruction for Sparse View X-ray Computed Tomography
With the availability of more powerful computers, iterative reconstruction algorithms are the subject of an ongoing work in the design of more efficient reconstruction algorithms for X-ray computed tomography. In this work, we show how two analytical reconstruction algorithms can be improved by correcting the corresponding reconstructions using a randomized iterative reconstruction algorithm. T...
متن کاملSparse-View X-Ray CT Reconstruction Using 𝓵1 Prior with Learned Transform
A major challenge in X-ray computed tomography (CT) is reducing radiation dose while maintaining high quality of reconstructed images. To reduce the radiation dose, one can reduce the number of projection views (sparse-view CT); however, it becomes difficult to achieve high quality image reconstruction as the number of projection views decreases. Researchers have applied the concept of learning...
متن کاملSplit-Bregman-based sparse-view CT reconstruction
Total variation minimization has been extensively researched for image denoising and sparse view reconstruction. These methods show superior denoising performance for simple images with little texture, but result in texture information loss when applied to more complex images. It could thus be beneficial to use other regularizers within medical imaging. We propose a general regularization metho...
